Italo-Celtic dialect base words?

Does anyone have information on a "reconstructed" Italo-Celtic dialect word set? What I'm interested in are words that are expected to have a common root across Italic and Celtic languages but not in other Centum IE languages.

What words first show up in probable Italo-Celtic dialects but are beyond the basic PIE lexicon?

This would help in overlaying genetic and archaeological information and might provide clues as to the expansion of certain groups of people that became common across western Europe.
